Wearing protective gear and ensuring proper ventilation are crucial safety measures for a cosmetologist when using chemical products. Protective gear, such as gloves, masks, and goggles, helps to guard against skin irritation, respiratory issues, and chemical burns, which can occur when handling these substances. Proper ventilation is essential to minimize the inhalation of potentially harmful fumes and vapors that may be released during the application of chemical products. This combination of protective practices helps ensure both the safety of the cosmetologist and the well-being of their clients, creating a safer environment during chemical treatments.

The other options pose risks; only using products on client request does not account for safety measures that should always be followed. Applying excessive amounts of chemicals can lead to negative reactions or damage, and mixing products without checking can create harmful interactions, jeopardizing safety.
